Daily use of lithium batteries and the consequences of overcharging

Pay attention to the daily use of lithium batteries and the consequences of overcharging. Some drivers often forget to charge their lithium batteries. Because the lithium battery is not fully charged in the car, it is easy to cause the steel plate to vulcanize; at the same time, the charge and discharge in use are not balanced. If the discharge is greater than the charge, the lithium battery will be in a long-term power-off state, and the lithium battery plate will slowly vulcanize. This chronic vulcanization will cause the charging capacity of the lithium battery to continue to decline until it cannot be started, which greatly shortens the life of the lithium battery. The order of lithium batteries for forklifts in Dalian Development Zone is reversed. Connect the positive electrode first and then the negative electrode. What should you pay attention to in daily use of the lithium battery? The reporter interviewed Changqing Lithium Battery Co., Ltd. Deputy General Manager Mr. Zhou and General Manager Xu Jingxiong of Guangzhou Guangxiongsheng Industry and Trade Co., Ltd. According to Zhou's analysis, lithium batteries can be divided into starting batteries and traction batteries. The starting battery packs include maintenance-free batteries and water-filled batteries. In order to reduce the active material on the pole plate of the lithium battery in time, reduce the vulcanization of the pole plate, improve the charging capacity of the lithium battery, and prolong the service life of the lithium battery, the lithium battery should be charged regularly during use. Instead, connect the positive electrode, the negative electrode, the positive electrode of the battery power supply of the positive electrode and the negative electrode of the battery power supply of the negative electrode, and then the initial charging is performed in two stages: first, the initial charging current of the charged electrolyte releases foam, and the single battery voltage rises to 2.3- -2.4v. Then reduce the current to half of the initial charging current, and continue charging until the electrolyte is fully foamed and the voltage is stable for 3 hours. The total charging time is about 45~65h. Lithium batteries are often overcharged. Even if the charging current is small, the electrolyte will boil for a long time. In addition to the fine particles on the surface of the active material, it is also easy to fall off, causing the mesh to be over-oxidized, causing the active material to be loosely separated from the mesh. Sometimes I find that the power on the road is not enough. First connect the positive pole of the battery to the positive pole of the power supply, and connect the negative pole of the battery to the negative pole of the power supply, and then perform the initial charging in two steps. First, use the initial charging current to charge the electrolyte and release bubbles, and the single cell voltage rises to 2.3-2.4v . Then reduce the current to half of the initial charging current, and continue charging until the electrolyte is fully foamed and the voltage is stable for 3 hours. The total charging time is about 45~65h. Because the positive and negative materials of lithium batteries are different, in addition to the active material, the anode also contains barium sulfate, humic acid, carbon black, rosin and other substances to prevent anode shrinkage and oxidation. Forklift lithium batteries in Dalian Development Zone are just the opposite. Connect the positive electrode first, and then the negative electrode. Therefore, pay attention to the polarity when charging. We cannot reverse the polar charge. Nowadays, there are more and more electronic devices in cars. When using these electronic devices, users should try not to overload the lithium battery. Lithium battery overload will reduce the service life of the lithium battery. It is very important to master the correct method of charging the lithium battery. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
